REVERSING MEcnANisr/L- Specification of Letters Patent.

Patented Nov.1t6,1t915.

Application filed June 19, 1913. Serial No. 774,581.

new and useful Improvements in Reversing Mechanisms; and I do herebydeclare the following to be a full, clear, and exact description of thesame, reference being had to the accompanying drawmgs, forming a part ofthis specification, and to the referencenumerals marked thereon.

My present invention relates to reversing mechanisms adapted foremployment with various types of machinery, where it is desirable tomove an element alternately in opposite directions, such, for instance,aswashing machines used for laundry purposes, in which the washingcylinder is rotated first in one direction and then in the other for apredetermined number of revolutions, and it has for its object toprovide an improved construction and arrangement by which the parts,where friction is setup, may run in a bath of oil and an easier and moreregular movement is obtained for the elements whose direction ofmovement is reversed at predetermined intervals.

To these and other ends the invention consists in certain improvementsand combinations of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is a view in side elevation of a preferredembodiment of my invention, showing its application to a washingmachine, a portion of which is broken away; Fig.2 is a sectional view onthe line 2 -2 of Fig. 3; Fig. 3 is a sectional view on the line 3 3 ofFig. 2; Fig. 4 isa sectional view on the line 4 a of Fig. 3, and Fig. 5is a detail elevation showing the member for manually controlling thebelt shifter disengaged from the reversing gear.

Similar reference numerals throughout the several figures indicate thesame parts.

In the present embodiment of the inven tion, 1 designates the body of awashing machine of usual type, embodying a rotating cylinder whosemovement is reversed at predetermined inteiwals, and 2 is a gear wheelwhich is connected in any suitable manner with the cylinder of thewashing machine, although it will be understood that for the purposes ofmy invention, the gear wheel 2 might be an element of any mechanismwhich it is necessary to move alternately in opposite directions. Thegear wheel 2 is actuated by a shaft 3 having a pinion 4 in engagementtherewith. The shaft 3 is mounted in the bearing 5 of the support orbracket 6, which is fixedly attached to the body 1 and constitutes thedriven member of the present embodiment. Said shaft also carries a fixedpulley 7 and loose pulleys S.

9 designates oppositely driven belts which are adapted to be shifted soas to drive the fixed pulley 7 in one direction or the other or topermit the shaft 3 to remain idle, as shown in Fig. 1, and my presentinvention has to do more particularly with the means for shifting saidbelts alternately in opposite directions to secure this reversal ofmovement.

10 is the belt shifter provided with arms 11 which engage the respectivebelts, and which is slidably arranged on the guide post 12, the latterbeing suitably mounted upon the bracket 13, to be described more fullyhereinafter. The shifter 10 carries the arm 14, which forms a bearingfor the rotatable rod 15, the latter being attached to said arm 14, asshown in Figs. 1 and 4, and being journaled in the stationary bearing16, within which it has a sliding as well as a rotating movement. Theshifter 10 is adapted to be manually operated by means of said rod 15,and to this end the latter is provided with a weighted handle portion 17to enable it to be turned. The rod 15 has fixed thereon a member 18which is provided with a pair of cam surfaces 19, and also has a notchor recess 20-for a purpose that will presently be made clear. The camsurfaces 19 are arranged for engagement with a pair of stationaryprojections 21, whereby when the rod 15 is rotated, said projectionswill cause a longitudinalmovement thereof sufficiently to bring bothbelts into engagement with the loose pulleys on the shaft 3. When themember 18 is in its normal position, as shown in Fig. 4, it is engagedby an actuator 22 having a pin 23 cooperating with the aforementionedrecess 20 and through the movement .making the corresponding belt 9sufiiciently wide to engage partially at all times with its loosepulley. The worm 24 engages with the wormgear 25, loosely disposed onthe bearing 26, the latter being adjustably secured in the casing 27,which completely incloses the bottom portion of the reversing gearingand is preferably integral with the bracket 13, said bracket being heldin position by means of the cup 28, which is serate of speed for allpositions.

cured within the aforesaid bearing 5 and receives the outer end of theshaft 3.

29 designates a cam formed on the sleeve 30 which is provided withsuitable projections engaging corresponding recessesin the worm gear 25whereby the cam is driven constantly with the worm gear. Said cam isoperatively associated with the actuator 22 whichis pivotally mounted at31, and in order to obtain properly equalized movement of the beltshifter in both directions, it is desirable to provide a compensatingmeans between the cam and the actuator. To this end, I prefer not toconnect the parts directly, but to afiord an indirect connection wherebyI may effect movement of the actuator 22 at substantially constant speedat every point of its movement. To this end, I provide a lever 32 whichis pivotally mounted at 33, and has a bifurcated end portion comprisingparallel arms 34, between which are arranged the roller bearings 35,disposed for engagement with the cam 29. It will be seen that by reasonof the relative positions of the cam 29 and the pivotal point 33, themovement of the end of the lever 32, or of the roller bearings, is verynearly in a straight horizontal line, its movement being atsubstantially a constant The movement of the lever 32 is communicated tothe actuator 22 by connecting said parts in a suitable manner, and forthis purpose the actuator is preferably provided with a bifurcated tailpiece 36 having'projections 38 engaging in recesses 37 formed on thearms 34 of the lever 32.

39 is a lubricating wick secured in a suitable recess onthe actuator 22,and arranged to engage the edge of the cam 29, so as to supply thelatter constantly with oil.

I claim as my invention:

1. In a reversing mechanism, the combination with a rotary member, offast and loose pulleys mounted thereon, belts coeperating with thepulleys, a shifter for controlling the position of the belts, apivotally mounted actuator connected to the shifter, a pivotally mountedlever having connection with the actuator, and a cam in cooperativeengagement with said lever.

2. in a reversing mechanism, the combination with a rotary member, offast and loose pulleys mounted thereon, belts coeperating with thepulleys, a shifter for controlling the position of the belts, apivotally mounted actuator connected to the shifter, a cam for movingthe actuator, and an intermediate connecting device between the cam andthe actuator, said device being pivoted independently of the actuatorand having operative connection therewith, the cam having engagementwith the connecting device.

3. In a reversing mechanism, the comb1- nation with a rotary member, offast and loose pulleys mounted thereon, belts coeperating with saidpulleys, a shifter for controlling the position of the belts, a pivotedactuator connected to the shifter, a lever pivotally mountedindependently of the actuator and having connection therewith, and arotary cam arranged to engage and control the movements of said lever.
